Patent JP-H01235295-A (JP)
Title: Manufacture of electric laminated board
Inventor: SATO KOJI
IPC: H05K3/46
Filed: 1988-03-15
Abstract: PURPOSE:To improve the adhesion of through-hole plating to the surface of a resin on the inner circumference of a through-hole by using the resin, with which spheroidal inorganic fillers, mean grain size of which extends over a fixed value, or acicular inorganic fillers, mean length of which extends over a fixed value, is mixed as a resin to be infiltrated in a prepreg. CONSTITUTION:A plurality of metallic plates 2 which through-holes 1 are formed at through-hole forming positions are superposed through prepregs 3 employing a resin, with which spheroidal inorganic fillers, mean grain size of which extends over 5mum, or acicular inorganic fillers, mean length of which extends over 35mum, are blended, as an impregnation resin. The superposed material is heated and pressure-molded, the resin infiltrated in the prepregs is cured, and each metallic plate is laminated and bonded while the resin infiltrated in the prepregs is made to flow and filled into respective through-hole in the metallic plates and cured. Through-holes 5 are boring- worked in the sections of the resins 4 in the through-holes, and through-hole plating is executed onto the inner circumferences of the through-holes 5. Since the spheroidal or acicular inorganic fillers are compounded with the resin impregnated to the prepregs in said process, irregular roughened surfaces are shaped onto resin surfaces on the inner circumferences of the through-holes, thus the adhesion of through-hole plating is improved.
